vfp 3.0 win 95

when editing fields in a pageframe, how can you
make the text your inputting wrap automatically
to the next field or text box?

what is the best way when inserting a new record
from an array, to copy some fields, and yet leave
some fields blank?

I need a calculation button to compute 6 fields
doing both adding and subtracting. ie,

total materials+total labor =subtotal-deposit=grandtotal

Can I use replace grandtotal with ......??

Thanks and have a great holiday..
